This is a complete one-session scenario. Depending on player activity and GM style, run time should range from three to six hours. Seven pre-generated characters have been included, but original characters may be used to replace any or all pre-generates.

"To Kill A Monster" is an introduction to RuneQuest and Glorantha, with a focus on roleplaying, PC cleverness, and intuition. Simplified RQIII rules are recommended—the players should not have to struggle with the system. The GM is urged to use only as many rules as s/he is comfortable inflicting on the players. Of course, the scenario can also be run for experienced RuneQuest players. This is not an exercise in Gloranthan scholarship; it is an introduction to some Gloranthan elements only. The intention is to avoid frightening off players with a world that can be dauntingly complicated for the uninitiated.
